朋友合法入境后逾期居留，在一次移民局的突击行动中被抓住。与移民局达成自愿离境协议后，被放出来，应该在9０天内离境，但他并为离境。继续在美国生活了５年，现在打算与一美国公民结婚，指望通过婚姻获得绿卡。有谁知道这条路是否可行？
-Because he is under removal proceedings (deportation), he needs to get the waiver for the removal proceedings after he marries the US citizen. It is hard to get it done, so he had better hire an experirenced lawyer to help him out. Before he get the waiver, he can not get the green card.
